Be it known that I, ALBERT ,B, SIMON, a citizen of .the United States, and a resident of the cit useful Improvements in Fabric-Frames,-of

' which the following is a specification.

igure 1 is a back view of my frame and 1 its operating mechanism.

Fig. 2 is a detail of the operating mechanism with a'portion of the cover plate re- 7 moved to better disclose the moving parts.

Fig. 3 is a cross section of Fig. 2 through the center with certain of the parts shown in view. 7

V Fig. 4 is a detail of the manner of forming the ends of the lateral members to insure their sliding engagement,

Fig. 5 is a fragmentary sectional view of the connection between an end member and one of the moving parts.

Throughout the figures the same refer to identical parts.

The sides of the frame are indicated by the numerals 1, 2, 3, 4, to which I prefer to attach a plurality of clamps as 5, 6, 7 8,su1tably spaced, and which are used to clamp the edges of the fabric as at 9, 10; a portion only of the fabric being shown in the illustration. The sides 1, 2, 3, 1 aresupported respectively from central.members 11, 12, 13, 14 on which numerals are mounted the racks 15,16, 17 18 respectively, and which racks are in mesh with the pinion 19. This pinion is fixed to the shaft 20 such that the rotation of the said p1Il10I1 causes the simultaneous operation of the racks either to expand or contract the frame sides 1, 2 3, 4.- V

The shaft 20 is mounted'within the two plates 21, 22 which I prefer to form with the corner members as 23, 24. These corner members also serve to retain the spaced relation between the plates 21,. 22, and also serve as guides against which the racks operate on their faces opposite to the tooth side.

pin26, which may be used to engage any of the holes in the plate 21 as at 27 ora ratchet any desired and county of San ,FIELIICISQO, State of alifornia, have invented new and Specification of Letters Patent.- Patented 29 x Applicationflled an 10,1920. Serial 170,864,698. i 3

pawl, any other holding means,

whereby the arm or crank 25 maybe fixed in position, maybe employed. eferring 'to-Fig. 4, which shows one of the corners of the frame, the frame side members 3 and 4, are in loose slidable engagement and itwill be noted that one of these sides 3 is slotted loosely engage the tongue 29 of the side 4:, so

that all of the sides 'may be moved with respect to each other andwill be retained at alltimeswithin the same plane.

The operation is as follows: 1 The lever 25 is rotated in a contra-clockat 28 and adapted to.

. wise direction thereby drawing all the mem- 1 bers of the frame inwardor toward each 7 other. The clamps as'5, 6, 7, 8 are now affixed to the fabric all around its periphery. The crank 25 is now to be rotated in the clockwise direction until the fabric is stretched to the desired degree when the pin 26 is to be inserted in one'of the holes as 27 thus locking the frame in its expanded osition and with the fabric stretched. en

the desired stretching or .drying'is. com-' pleted the pin is removed when the frame members are loosened by the contra-clockwiserevolution of the'pinionwhen the fabric may be removed from the clips or clamps.

Attention is directed to the means that are provided wherebythe frame may readily be adapted to support itself and which consists of the feet 30, 31 and the back member 32 screwed into member 4 whereby the frame may be stood up like an easel with the member 1 on the bottom and the member 4 on the top. The feet and back member may, however, be located on'any of the other sides with equal facility.

The manner of joining'the sides to the rack operated members and to the back mem ber is preferably that of a screw thread on the member and a corresponding screw threaded socket in the side, as shown in the detail, Fig. 5. a

lVhere wet fabric is to be stretched it is advisable to use wood throughout the entire structure to preventstaining of the fabric,

and I prefer to make all'the parts, including the racks, members and sides, and the screw threads by which theyare engaged, of wood throughout, but'I do not wish to limit Inyself to any I claim: '1. In a frame for stretching and drying fabric and the like, a plurality of members specific material.

arranged polygonally and movable relatively at right angles to theirlength, a rack for each member'a'r'ranged at right angles thereto, a pinion to operate the racks and.

means supporting the racks about the pinion, substantially as a forth, j

2; In a frame forstretching and-drying v fabric and the like, a plurality of members arranged polygonally and movable relatively at'rightangles totheir length, a rack Y for each member arranged at right angles thereto, a pinion t0 operatethe racks and like, a quadrangular frame whose sides are each side and centrallyafiixed t ion substantially centrally disposed and en- I nd' for the purpose set i for drying fabric and the V relatiyely movable, a at right angles to gaging all the racks, and means for rotating the pinion whereby the sides are moved.
